Key Features and Specifications
The Simms G3 Guide Backpack boasts waterproof construction, ample capacity, comfortable design elements, and strategic external attachment points for versatile gear management.
Waterproof Construction & Materials
The Simms G3 Guide Backpack’s core strength lies in its robust waterproof construction. Utilizing durable, high-quality materials, this backpack is designed to withstand harsh conditions and keep your valuable gear dry. The roll-top closure system is a key feature, providing a secure and watertight seal against rain, splashes, and even full submersion.
Constructed with a tough TPU-coated fabric, the G3 Guide offers exceptional abrasion resistance, ensuring longevity even with frequent use and rough handling. The materials are carefully selected not only for their waterproof capabilities but also for their lightweight nature, contributing to overall comfort during extended use. Seams are fully taped to eliminate potential leak points, reinforcing the backpack’s waterproof integrity. This meticulous attention to detail guarantees reliable protection for your fly fishing essentials.
Capacity and Dimensions
The Simms G3 Guide Backpack strikes a balance between ample storage and a manageable size. Boasting a generous capacity, it provides sufficient space for essential fly fishing gear, including waders, jackets, fly boxes, and accessories. While specific dimensions can vary slightly, the backpack generally measures around 19”H x 12”W x 8”D, offering a substantial 30-liter volume.
This capacity allows anglers to comfortably carry everything needed for a full day on the water without feeling overly burdened. The thoughtfully designed interior and exterior pockets further enhance organization, preventing gear from shifting during movement. Despite its sizable capacity, the backpack’s streamlined profile ensures it remains relatively compact and doesn’t hinder mobility. It’s large enough for serious gear, yet remains practical for various fishing scenarios.
Weight and Comfort Considerations

The Simms G3 Guide Backpack aims to minimize strain during long days on the river. While a fully loaded pack will naturally increase weight, the backpack itself is designed with comfort in mind. It typically weighs around 3.5 pounds when empty, a reasonable weight for its robust construction and features.
Padded shoulder straps and a supportive back panel distribute weight evenly, reducing pressure points and enhancing comfort. An adjustable sternum strap and waist belt further contribute to a secure and customized fit. Some users note that the pack can become uncomfortable when heavily loaded, highlighting the importance of packing strategically. However, overall, the G3 Guide prioritizes angler comfort during extended use.
Color Options and Availability
The Simms G3 Guide Backpack is generally available in a range of color options to suit individual preferences. Historically, popular choices include colors like Anvil (a dark gray), and potentially seasonal or limited-edition variations. Availability can fluctuate depending on demand and retailer stock levels.
As of January 27, 2026, checking with authorized Simms dealers and online retailers is crucial to confirm current color availability. Popular retailers like Trident Fly Fishing and Bass Pro Shops typically carry the G3 Guide. Due to its popularity, certain colors may sell out quickly, especially during peak fishing seasons. Checking the Simms website directly is also recommended for the most up-to-date information.

Detailed Examination of Backpack Components
The Simms G3 Guide Backpack features a thoughtfully designed layout, including a main compartment, dedicated fly storage, tool pockets, and external attachment points for gear.
Main Compartment and Access
The core of the Simms G3 Guide Backpack lies in its spacious main compartment, designed to accommodate a substantial amount of gear for a full day on the water; Access is provided through a waterproof roll-top closure, a hallmark of the G3 series, ensuring contents remain dry even in challenging conditions. This roll-top design isn’t just about waterproofing; it also allows for variable compression, adapting to the volume of gear carried.
Internally, the compartment is relatively uncluttered, maximizing usable space. While not heavily subdivided with pockets within the main area, this simplicity allows for flexible organization based on the angler’s specific needs. The opening is wide enough to easily locate and retrieve items, even bulky ones like rain gear or extra layers. The durable materials used in construction contribute to the compartment’s longevity, resisting abrasion and wear from frequent use.
Dedicated Fly Box Storage
A standout feature of the Simms G3 Guide Backpack is its thoughtfully designed dedicated fly box storage. This isn’t simply an afterthought; it’s a specifically engineered pocket positioned for quick and easy access to essential fly selections. The pocket’s dimensions are optimized to accommodate standard-sized fly boxes, preventing them from rattling around loosely within the main compartment.
The interior of the fly box pocket is often lined with a soft material, protecting delicate flies from damage during transport. This attention to detail demonstrates Simms’ understanding of the needs of serious fly anglers. The placement of this pocket, typically on the exterior of the pack, allows for rapid fly changes without needing to fully open the main compartment, crucial during active fishing sessions.
Tool and Accessory Pockets
The Simms G3 Guide Backpack excels in providing ample and intelligently placed tool and accessory pockets. Beyond the main compartments, anglers will find a variety of pockets designed to keep essential gear organized and readily accessible. These include dedicated slots for pliers, nippers, floatant, and other frequently used tools. Many pockets feature elastic loops or dividers to secure items and prevent them from shifting during movement.
External stretch-woven pockets offer convenient storage for rain gear or quick-access items like leader material. The strategic placement of these pockets ensures that tools are within easy reach without hindering movement or comfort. Simms understands that efficient organization is key to a successful day on the water, and the G3 Guide’s pocket system reflects this philosophy.
Hydration Compatibility
Staying hydrated is crucial during long days on the water, and the Simms G3 Guide Backpack thoughtfully addresses this need with excellent hydration compatibility. The backpack features a dedicated hydration sleeve, capable of comfortably accommodating most standard hydration reservoirs. A port for the drinking tube allows for hands-free hydration without needing to remove the pack.
This design element ensures anglers can easily access water while focusing on fishing. The sleeve is strategically positioned to maintain balance and prevent sloshing. Many users appreciate this feature, especially during strenuous hikes to remote fishing spots. It’s a simple, yet vital, inclusion that enhances the overall usability and convenience of the G3 Guide Backpack.
External Attachment Points & Lash Tabs
The Simms G3 Guide Backpack excels in versatility, largely due to its abundance of external attachment points and strategically placed lash tabs. These features allow anglers to securely carry bulky items like trekking poles, wading staffs, or even additional gear externally, freeing up valuable space inside the main compartment.
Multiple daisy chains and robust lash tabs are integrated into the backpack’s design, providing numerous options for customization and gear organization. This is particularly useful for adapting the pack to different fishing scenarios and personal preferences. Anglers consistently praise the secure hold these attachment points offer, even during challenging terrain; It’s a key element contributing to the pack’s overall functionality.
